Tested: Nine Brilliant, High-Powered Lights

Light & Motion Seca 1700 Race

6 / 9

This powerful, lightweight option pumps out 1,700 lumens while tipping the scales at just 343 grams. With six bulbs, this was one of the brighter lights we tested. Beam orientation also drew high marks. Instead of pointing straight ahead, the majority of the light is angled downward and to the sides, meaning less wasted output. Light output can be set in either cruise mode, which has three settings, or race mode, which has just low and high levels. Light & Motion claims run time is 90 minutes on high, or 2:45 at the medium 850-lumen setting. We liked the handlebar mount, which uses a rubber strap that is easier to use that many of the O-ring mounts found on other models. The Seca 1700 also comes with a helmet strap. We just wish that Light & Motion included a short cord for mounting the battery to your frame. Instead, the unit comes with just one long cord.
